Alchornea (Alchornea cordifolia): Benefits, Dosage, Safety & Evidence

Questions fréquentes

How does Alchornea cordifolia work as an antimicrobial?

Alchornea cordifolia contains bioactive compounds including alchorneine, gentisic acid, gallic acid, and ellagic acid that demonstrate antimicrobial properties. These compounds work through multiple mechanisms, including disrupting bacterial cell membranes and inhibiting microbial enzyme activity. Laboratory studies show activity against various bacteria and fungi, though human clinical trials are limited. Evidence Level: C.

Does Alchornea interact with any medications?

There is limited research on Alchornea cordifolia drug interactions. Due to its antimicrobial properties, it may potentially interfere with antibiotic medications. The plant contains tannins and phenolic compounds that could affect absorption of certain drugs. Patients taking prescription antibiotics, immunosuppressants, or medications metabolized by the liver should consult a healthcare provider before using Alchornea. Evidence Level: D (theoretical).

What is the recommended dosage for Alchornea cordifolia?

The typical adult dosage for Alchornea cordifolia is 3-5 grams of dried leaf prepared as a tea, or 2-4 mL of tincture taken up to three times daily. Traditional preparations vary by region and condition being treated. Standardized commercial products are limited. Always follow product-specific instructions or consult a qualified herbalist for personalized dosing. Evidence Level: Traditional/C.

Is Alchornea safe during pregnancy and breastfeeding?

Alchornea cordifolia is contraindicated during pregnancy and breastfeeding. Traditional use and limited animal studies suggest it may stimulate uterine contractions, posing a risk of miscarriage or premature labor. Nursing mothers should also avoid Alchornea as safety data for infants is lacking. Women who are pregnant, planning pregnancy, or breastfeeding should not use this herb. Evidence Level: D (theoretical risk).

Can Alchornea be used for wound infections?

Alchornea cordifolia has a long history of traditional use for treating wound infections in West African medicine. Laboratory studies demonstrate antimicrobial activity against bacteria commonly associated with wound infections, including Staphylococcus species. The leaves are typically applied topically as a poultice or wash. While promising, clinical evidence in humans remains limited. Evidence Level: C.

Is Alchornea effective for treating diarrhea?

Alchornea cordifolia is traditionally used to treat diarrhea in West African folk medicine. The plant contains tannins and antimicrobial compounds that may help reduce intestinal inflammation and combat infectious pathogens causing diarrhea. Laboratory studies support some antimicrobial activity, but controlled human trials are lacking. It should not replace standard medical treatment for severe or persistent diarrhea. Evidence Level: C.

Résumé

Alchornea cordifolia is a medicinal plant widely distributed in tropical Africa, used traditionally to treat a variety of infectious, inflammatory, and reproductive conditions [PMID:27296085].

Contexte

Alchornea cordifolia (Schumach. & Thonn.) Muell. Arg., also known as Christmas Bush, is a member of the Euphorbiaceae family [PMID:27296085, PMID:35456270].

Usages traditionnels

It is used extensively in traditional medicine for coughs, gonorrhoea, infertility, prostatitis, bacterial infections, diarrhoea, ulcers, pain, inflammation, fever, bronchial troubles [PMID:27296085], and sickle cell anaemia [PMID:35456270].

Composés actifs

Identified compounds include quercitrin (quercetin 3-rhamnoside) [PMID:35456270], methylgallate [PMID:30886338], eugenol and cadinol [PMID:21707250], and alchornoic acid ((+)cis-14,15-epoxy-cis-11-eicosenoic acid) found in seed oil [PMID:27519847]. The plant also contains phenolics, flavonoids, terpenoids, alkaloids, tannins, and anthraquinones [PMID:11163946, PMID:28676114].

Mécanisme d'action

Quercitrin inhibits the polymerisation of isolated HbS and suppresses erythrocyte sickling [PMID:35456270]. Polysaccharides from the leaves induce monocyte/macrophage nitric oxide (NO) and cytokine production via activation of mitogen activated protein kinases (MAPK) and nuclear factor kappa B [PMID:23291534]. Methylgallate demonstrates potency against HIV-1 integrase [PMID:30886338].
